My invention relates to pull-out mech-- anisms for windmills of the type having a p1voted vane, My, pull-out mechanism is designed partlcularly for useln connection -35 with windmills havingthe gearing and on;

ing system described in my copending appli 'cation, Serial Number 7185895, filed June 9,

' 1924, but it is adapted for use on any or all windmills of the general type.

In brief, the object of my invention is the;

provision of a pull-out mechanism which is entirely outside the lubricant container and themast so that neither can interfere with or be interfered by the operation of the pullout mechanism, and so that all parts of the pull-out mechanism are within easy access V out mechanism. r Figure 2 1s aLplan view'of the-parts and plain sight at all times; Other objects will be referred to and discussed in greater detail in the following description I Referring now to the drawings forming part of my application, and inwhich like numerals designate like parts in the description, V Figure 1 is a side elevation of the windmill head showing also a portion of my pullshown in Fig'urell Figure 3 is, a'view in perspective of the upper portion of the windmill tower and of the mast, showing particularly the swivel mechanism whereby the pull-out chains and cords are made to \operate entirely outside the tubular mast. i V V Figure 4; isa view in perspective of a por- 'tion of the collar surrounding the tubular mast at its upper 'extremity and showing the guideway for the pull-out chain.

p The Windmill includes :the usual tower :10' with the top casting 11 boltedthereto. The

top casting 111 carries the turntable ,12' onfla ball race and the}turntable.supports the' v workingparts ofthe wiiidmill..f(Themaincasting 1-3 jsery es both asian .oil leservoi perspective view of thelenand as a support for bearings and pivots of Under as e part l tf is an integral partof the casting 13 and its'inner surfaceissemicylindrical and of the same diameter as that of'the mast. The part 14" is complementary to-the part 14? and is secured thereto by means of bolts 10 andfwhen the parts are thus assembledlthe 'main casting 1 3 is in effect integral with the mast 15 and'the collar 1a. The mast- 15 is and nuts or other suitable securing means. The collar 14 is clamped tightly on the mast 1 rigidly secured in the turn table 12, so that 1 I the'entire weight of the working parts of the windmill is carried on the turn table and; its ball race. ThefmastlS passes throughand is anchored in the-spider 16 in such; a

'way as to maintain the mast inperpendicular relation and to prevent endwisemovement but at the same time permitting the mast to turn.

' The hood or cowl 17 covers the main ing 13 and the working parts of the windmill its principal function being to prevent the entrance of water, dust and other foreign Tie matter. into the lubricantcontainer. vane arm 1811s connected by means of the 'verticalpivot 19 to the main casting 13. In

order to prevent thesagging of. the vane and the vane arm '18, I provide a supporting brace 20 which is connected to the vane arm at ornear its forward extremity and indirectly to the casting as shown in Figure l. 'The vane arm18is provided with a right angled {projection 21 carrying ,apbum per' spring 22 at its free end. The spring 23 and its connectionscooperate with the'a-rmi 21' to normally} maintain the vane arm in;

substantial alignment with the main drive shaft 24;

otherwise freeito swing through an arc of" rIl 'pr v -le' the; chain 5;..a i the o n' t ene I c flirt, gb The vane arm, while normally held by they T spring 23 in a more or less fixed position, is

The chain passes over the sheaves 26 and 28 down through the aligning pas sageways. I

Secured to the mast underneath the top casting; '11 is swivel which permits free oscillation or rotation on a vertical axis of the niaincasting 1S and the parts connected theretoybnt which (l-e. itely limits the oscillation otthe pull-out parts underneath the swivel. The collars'SQ and Ell are both secured to rotate with the IDZLSE 15, but toprevent a y possibility of ippage I provide a rod 532 which passes through aligning ver- The the rod-32 anchored in the upper end or? 'ed in "the clamp 33 which tightly enthe n'iast at a point below t re swivel. 3'0 and 31 are thus secured ancho anti the rod 82, the lower/limit of the Sllilm niovenient being determined by the posi ion or the clamp 32-3. The c llar 30 has anupwardlyproiecting hook 3a forsecu'ring the lower e 1 ol' the'ch'ain 25. v

Interlocked with the inner collars 30 and, 31 are the outencollars 35 and 36. For convenience in assembling and when making adjustments and i -pairs, the outer collars are tonnelot semicircular halves, each half heing provided'with'ears '3? having registeres for the reception 'of bolts or ihle' securing means. The "outer collars-"are grooved on their inner periphe its, the grooves be e 'nro'e'ctin p r webs on the outer the inner toners as shown'in ach pair of collars theretofe'in- 1: which is slida'blyjand V tahly inou on the mast andan celiarwsich is n o'nsl-idably and rota-tat se med"toftiisiimeir'collan 'T "e eater PS "connect d "with each "other 't'y means "oi -the rbjds 38 passin he lower end of the rod-being adapted to receive 1 clamp 33, The tension, 'on' the chain causes the movement of the vane a-rni 18bit its pivot. 'lhewire 39 may then be secured in the down position and when it 1S desired to again start. the windmill it is only necessary to release the wire 39. f l vhen the pullout. Wire 39 isreleased the spring23 draws the vane arm 10 back into alignment with the axis of the wind wheel, the movement 1 i losing trans 'nitted throughthe chaiii 25 to draw the swivel "upwardly to its elevated .position. The opening movement otsthe' vane arm 18 is the casting l3 and the bumper. spring 22 stopped when the arm 21 strikes takes up tne shockot the impact and thus pi'ev entsinjury to the various parts. When the parts above the tower turn in the wind abontthe vertical aXis,,. the chain 25'and the collars "and 31 are forced to move-about the same 'vertical'axis but the collars and 86 remain practically stationary so that the pull-out wire 39 'Wl'll not be wound and twisted on the mast. Therenecessarilyis a certain" degree of friction between theinner and-outer collars oi. the swivel with the result that there is a limitedainount of arcuate movement of the outer'collars when the direetion of the wind changes,bnt thisarcuate movement is held Within definite limits by the arm %0 secured in thedownwardly pro 7 'jecting ear ll of the collar 36, thelarin being of suilicient length to abut against two 01 the posts of the towero The oscillation of the outer portion of the swivel is thus limited to an arc of less-than a quadrant.

Myinvention does away-entirely with the necessityot interference between the lubricating device and the pull-out mechanism since all parts of the pull-out mechanism are positioned entirely outside the lubricant chamber. All parts offthe-pull-out mechanism are moreover clearly visible from the ground {so that the need of adjustments or repairs can be instantly recognized and located in "time to prevent possible serious da age. VVh'en such adjustments or repairs are required, 'itwill be found thatfallvparts arewvithin easy -iaocess and that the adjustments "and iepai'rsa'can be made without disfasc' enibling'the windmill or any portions of the windniillp i 1 '1 "It is evident that various changes, varia ise,

511d; 1nodifications might be resorted to without departing from the spirit and scope of my invention and hence I do not a wish to limit myself to the exact disclosures thereof. 1

Having thus described my invention in terms which will be readily understood by others skilled in the art to which it pertains, what I believe to be new anddesire to secure by Letters Patent of the United States i is V 1. In a Windmill, an integral and seamless casing which is adapted to retain lubricating oil and which is adapted also to support the working parts of the windmill, and a clamp for securlng a downwardly pro ect1ng mast to the said casing, said clamp comprising two semicylindrical members, one only of said members being integral with said casing, and means for uniting said members in clamping relation about the upper extremity 1 of the mast, said clamp being positioned substantiallybeneath the center of mass of the.

casing with the working parts of the windmill secured thereto. 7

windmill, and manually operable means for causing said vane to swing on itspivot and out of its normal position, said last named means being positioned outsidethe mast and outsidethe casing, there being a passageway therefor between the clamp and the upper portion of the mast.
